MVI69E-MBS Modbus Serial Enhanced Communication Module

MVI69E-MBS Modbus Serial Enhanced Communication Module

The MVI69E-MBS Modbus Serial module for CompactLogix™ is designed for all applications requiring Modbus Serial connectivity. This module comes with an Add-on Profile and an Add-on Instruction to reduce commissioning time. The MVI69E-MBS has two serial ports and can support both Master and/or Slave connectivity to interface with a variety of devices using the Modbus Protocol.

A conformal coating option is available for this product.

Features and Benefits
